VORAMER MN 2314 Prepolymer
is a highly-processable, cost-effective polyurethane solution for formulating concrete adhesives and sealants.
2) was a complimentary supply from SABIC-IP and was made by melt polycondensation with the same catalyst content used to prepare the prepolymer
With the right combination of urethane building blocks, and the unique structure of hard segments generated from the low free (LF) monomer prepolymer
, the resulting thermoplastic urethanes have reached a higher performance level.
Huntsman Polyurethanes says it is aiming Suprasec 2154 prepolymer
at applications where passive fire prevention is required, for example in coating concrete and steel structures in multi-storey car parks.
